About MakerKiln
Workshop calculators that do their work in your browser, not on a server.
What this is
MakerKiln is a set of free calculators for people who make things. 3D print cost, filament and spool math, pricing, cut lists, and more as the set grows. Each tool is one page. It loads fast, works out the numbers as you type, and keeps your shop's settings in your own browser so they're there next time.
Everything is plain JavaScript running in your tab. No server does the math, there's no account, and nothing you type leaves your machine. That's why a tool keeps working once it has loaded, out in the shop where the Wi-Fi doesn't reach.
How the numbers are chosen
The presets, things like printer wattage, machine life and material prices, are typical published or community-measured figures, and you can change every one. They give you a sensible starting point in one click. Your own metered and weighed numbers always beat ours, and the tool keeps whatever you type.
Why we show our work
A number on its own is the easy part. Telling you what it means is the work. So each tool here says where a figure is exact and where it is a starting point to test on scrap, and it hands you the real levers instead of one tidy answer. Take the metal weight tool. The alloy densities already account for the mix, because an alloy is a blend of metals and we use the finished density. A specific grade shifts it a little, and a true composite like carbon fiber has no fixed density at all, since it rides on the fiber to resin ratio. So there is a Custom box for both, and a separate tool to work a composite out. We would rather give you the honest picture than a clean number that is quietly wrong.
The Kiln family
MakerKiln is one of five Kiln tools. The others are FileKiln for file converters, GradeKiln for GPA calculators, ShapeKiln for design asset generators, and OfficeKiln for office document builders. All five work the same way. The work happens in your browser, and what you type is nobody's business but yours.
